springboot笔记(9)单元测试

1.创建springboot项目

引入spring web依赖就行

2.service的测试

编写service

@Service
public class HelloService {

    public String sayHello(String s){
        return "hello "+ s;
    }
}

编写测试调用service

@Autowired
HelloService helloService;
 @Test
    void contextLoads() {
        String s = helloService.sayHello("chenyp");
    }

3.controller测试

1.编写2个controller分别返回string和json对象

	@GetMapping("/hello")
   public String sayHello(String name){
       return "hello "+name;
   }
   @PostMapping("/book")
   public Book sayHello2(@RequestBody Book book){
       return book;
   }

2.编写book类

	private Integer id;
    private String name;
    private String author;
    //get set方法
    //tostring

3.测试方法

@Autowired
WebApplicationContext wac;
MockMvc mockMvc;
@BeforeEach
    void before(){
        mockMvc= MockMvcBuilders.webAppContextSetup(wac).build();
    }

返回string的方法

@Test
    void test1() throws Exception {
        MvcResult mvcResult = mockMvc.perform(
                MockMvcRequestBuilders.get("/hello")
                        .contentType(MediaType.APPLICATION_FORM_URLENCODED)
                        .param("name", "chenyp"))
                .andExpect(MockMvcResultMatchers.status().isOk())
                .andDo(MockMvcResultHandlers.print())
                .andReturn();
        System.out.println(mvcResult.getResponse().getContentAsString());
    }

返回json对象方法

@Test
    void test2() throws Exception {
        Book book=new Book();
        book.setId(9);
        book.setAuthor("罗贯中");
        book.setName("三国演义");
        String s=new ObjectMapper().writeValueAsString(book);
        MvcResult mvcResult = mockMvc.perform(
                MockMvcRequestBuilders.post("/book")
                        .contentType(MediaType.APPLICATION_JSON)
                        .content(s))
                .andExpect(MockMvcResultMatchers.status().isOk())
                .andReturn();
        System.out.println(mvcResult.getResponse().getContentAsString());
    }

4.json测试

//在test类同级文件下写入json文件
{"id": 9,"name": "三国演义","author": "罗贯中"}

<resources>
   <resource>
       <directory>src/test/java</directory>
       <includes>
           <include>**/*.json</include>
       </includes>
   </resource>
</resources>

测试

@JsonTest
class Test2ApplicationTests {

    @Autowired
    JacksonTester<Book> jacksonTester;

    //序列化
    @Test
    void contextLoads() throws Exception {
        Book book=new Book();
        book.setId(9);
        book.setAuthor("罗贯中");
        book.setName("三国演义");
        Assertions.assertThat(jacksonTester.write(book))
                .isEqualToJson("book.json");
        System.out.println("三国演义");
    }

    //反序列化
    @Test
     void  testDeserialize() throws IOException {
        String content ="{\"id\": 9,\"name\": \"三国演义\",\"author\": \"罗贯中\"}";
        Assertions.assertThat(jacksonTester.parseObject(content).getName())
                .isEqualTo("三国演义");
    }
}
